Description
LABOCAP-caps with gripping knob in red are chrome-nickel steel closures sized for glass vessels with a diameter of 15/16 mm. They serve as practical accessories for culture vials and related glassware in microbiology, molecular biology and cell-culture laboratories, providing a firm metal cover during sample handling, incubation and short-term storage. The gripping knob supports controlled fitting and removal, which is useful when working with multiple tubes or when protective gloves reduce finger grip. Finished in red for clear visual sorting beside other LABOCAP colours, these caps are produced in chrome-nickel steel and belong to the range from manufacturer ROTH SELECTION. Each unit is offered as a pack of 100 pieces weighing 0,605 kg in total, convenient for restocking shared culture-media benches and teaching laboratories. Matched to glass diameters of 15/16 mm, the red LABOCAP-caps with gripping knob integrate into existing labware systems for culture vials without requiring special adapters. Choose them when colour-coded, knob-equipped metal caps are needed for smaller-diameter glass culture tubes in routine laboratory work.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about LABOCAP-caps with gripping knob, red, chrome-nikkel steel, f. glass. Ø 15/16mm
What is this article?
LABOCAP-caps with gripping knob, red, chrome-nikkel steel, f. glass. Ø 15/16mm is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biological buffers (Tris, HEPES, MOPS), inside Buffers & pH solutions, in Lab chemicals.
Tris, HEPES, MOPS and their relatives hold pH in a range that cells and proteins tolerate, with a pKa near the working pH. The useful range is roughly one unit either side of the pKa. A phosphate buffer and Tris are not interchangeable in a method that names one of them, because the ion itself has effects.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
